Referring to the drawings in detail, particularly Figures 1 to 15, inclusive, A designates generally the apparatus constructed in accordance with the invention and involves an outside frame It, an inside frame H and a filtering pack carrier l2, respectively, these frames being formed with open centers. The outside frame III at one end is provided with a fixed holding strip l3 while at the other end is a shiftable holding strip H, the latter working within a channel l5 and is acted upon by coiled springs |6 which urge this strip |4 outwardly of the channel l5. These strips are adapted for engagement between parting strips (not shown) in a window frame (not shown) for the detachable securing of the apparatus A within the latter. The top and bottom edges of this frame are flanged as at IT and I8, respectively, for the proper fitting of the apparatus with the strips I3 and M in the window frame although the said apparatus is adaptable for fitting within a framed opening within an enclosure wall (not shown). The strip I4 is fitted'with a handle I8 slidable in slots I9 so as to retract the said strip H by hand when it is desired to remove the apparatus from the window frame when being held therein by the strips l3 and I4. This handle I9 is readily accessible at the inner side of the frame I.

The frame II is attached to the frame III by side hinges for relative movement thereto. The filtering carrier I2 is adapted for interfitting in the frame l0 and is swingingly connected thereto by hinges 2|, the carrier being open at its top and is internally channeled at its bottom and sides for the slidable interfitting therewith of a filtering pack 22, preferably of fibrous oiled filling 23 for catching dust or other sediment, although the said filler may be of glass, wool or fibrous material coated with a sticky material such as petrolatum. The pack is removably insertable through theopen top of said carrier, the latter being swingingly supported enables easy access thereto for cleaning purposes of the pack by a vacuum cleaner or other device. The carrier in the interfitting thereof in the frame I9 is held interfitted by a frictional latch or other latching device (not shown).

The frame ID has arranged at its open center horizontally disposed swingable louvers 24 pivoted about horizontal axes and which in the series thereof through linkage 25 and a lever 26 cooperating therewith are susceptible of manual adjustment by a finger piece 21 of a set screw kind, which operates through a clearance or slot 29 provided in one end of the said frame II). In this manner the louvers 24 can be readily held in adjusted position for controlling the air flow therebetween and through the apparatus A in the use of the latter. These louvers 24 under adjustment in the closing thereof can be rendered airtight to exclude circulation of air through the apparatus, as is clearly shown in Figure 9 of the drawings.

The frame I I has its open center divided by a middle vertically disposed dividing piece 29 providing separated openings 30 therein and in these openings are arranged independent groups of vertically disposed horizontally swingable louvers 3|. Those louvers 3| of both groups innermost of such groups or next to the strips 29 are adapted to seat within channels 32 in said strips 29 on the closing of both groups of louvers so as to render the openings 36 airtight, as will be apparent from Figure 15 of the drawings. Each group of louvers has each louver therein susceptible of individual adjustment at 33 to regulate one with respect to the other and this adjustment 33 is included with the linkage 34 and tuming crank 35, respectively, for the turning of the louvers of each group. Each linkage 34 is actuated by a control 36 including a hand throw knob 31 fitted at one end of the frame Thus the groups of louvers 3| can be adjusted independently of each other and manually by the turning of the knob 31 conveniently located at one end of the frame The frame carries a finger-engaging grip 39 so that it can be conveniently swu'ng for the opening and closing thereof with respect to the frame l0.

The frame ID at the inner face thereof about the open center of the same is built with a. marginal flange 39 and the frame H is of a size to match this flange so as to be substantially flush with the other side faces thereof. The frame H is equipped with a suitable friction latching device (not shown) so that it can be latched when in closing relation to the section III.

The vertically disposed louvers 3| in the respective groups enable control under adjustment of such louvers of the directional flow of air through the apparatus A to within an enclosure.

The strip I4 is held against displacement in the channel |5 at the end of the frame ID by guide pins 46 fitting the said frame and strip as is clearly shown in Figure 4 of the drawings.

The springs. l6 are counterseated at 4| in the strip l4, which also has guide wings 42 and 43 .open position.

The filtering pack 22 in the arrangement of the carrier |2 will be interposed with relation to the louvers 24 and 3| when the carrier interflts the frame l9 and the frame being in closed position thereto so that air passing through the apparatus from without to within an enclosure will flow through the filtering pack 22 for the conditioning of the same. The adjustment of the louvers regulates ventilation through the said,

apparatus.

In Figures 16 and 17 of the drawings there is shown a modification of the invention wherein the louvered outside frame 41, which in its construction is identical to the frame III, at the inner side thereof has swingingly connected thereto a box-like body 48 open at the innermost side of the same while at the outermost side is a swinging plate-like door 49 provided with a substantially-square shaped opening 59 therein while at opposite sides of this opening are verti-- cally arranged slots 5|, these receiving headed nut-carrying bolts or the like fasteners 52 which are engaged in channeled slides or runners 53 disposed against the inner face of the door 49. These bolts 52 are fixed in a plate-like shutter 54 having a central opening 55, the shutter being susceptible of vertical adjustment relative to the door 49 with which it is fitted so that the opening 55 therein can be changed in its position so that it will be in confronting relation to a bladed fan wheel 56 of an electric motor type portable fan 51 which is adapted to be placed within the body 46 for support thereby as is clearly shown in Figure 17 of the drawings. This adjustment of the shutter 54 is for the purpose of promptly locating the opening 55 therein where fans of different heights are used in the apparatus or when it is desired to vary the point of location of 7 mom-1o such opening 58 for changing the outlet flow of air from the apparatus in a vertical direction.

The body 48 is detachably bolted or otherwise separably fastened, as at 58, to the frame 41 in a marginally matched relationship thereto. The fan 51 is for circulation of air through the apparatus drawing it in from the front or the outside to within an enclosure.

The frame 41 is equipped with a filter carrier and filtering pack identical to the carrier l2 and the pack 22 hereinbefore described.

Hinged at 59 for horizontal swinging movement is the inside louvered frame 68, being identical in construction to the frame ll although this frame 60 can be entirely dispensed with if found desirable, the louvers thereof being indicated at 8| while the'louvers of the frame 41 are indicated at 62, respectively. The door 49 hinged -to the body 48 can be opened outwardly to give access to the interior of said body when the frame should the occasion require and this body 48 can be equipped with suitable electrical connections for supplying current to the fan for the operation thereof.
